Well, with the advanced maps there is hours of more fun. And the internet is filled with custom maps and mods. And believe me or not, some are very good, like this one http://portalmaps.wecreatestuff.com

So I just finished translating Ep 33.
I hope I didn't forget any mistake. You're welcome to check it.
There's some thing I'm not sure of:
99
00:04:33,942 --> 00:04:39,346
Why would you have two sets of
ENORMOUS pistons slamming into each other like that?
that I translated in
99
00:04:33,942 --> 00:04:39,346
Pourquoi avoir deux ÉNORMES pistons
se claquer comme ça ?
but I wasn't sure about how to translate "slamming". Any help is appraciated
Edit: j'ai corrigé, merci Altom.

Hello,
I just translated the Episode 34.
I think it's good, but maybe someone should double check to see if there is no mistakes.
I study English at university and translating Freeman's Mind in french is kind of a good practice, so I think I'll do some more episode later if you think this one is any good (hope there are french viewers here).
